Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the contributions from the speakers at the NATO Advanced Research Workshop on "Structure of the Photosynthetic Bacterial Reaction Center X-ray Crystallography and Optical Spectroscopy with Polarized Light" which was held at the "Maison d'Hotes" of the Centre d'Etudes Nucleaires de Cadarache in the South of France, 20-25 September, 1987. This meeting continued in the spirit of a previous workshop which took place in Feldafing (FRG), March 1985. Photosynthetic reaction centers are intrinsic membrane proteins which, by performing a photoinduced transmembrane charge separation, are responsible for the conversion and storage of solar energy. Since the pioneering work of Reed and Clayton (1968) on the isolation of the reaction center from photosynthetic bacteria, optical spectroscopy with polarized light has been one of the main tools used to investigate the geometrical arrangement of the various chromophores in these systems. The recent elucidation by X-ray crystallography of the structure of several bacterial reaction centers, a breakthrough initiated by Michel and Deisenhofer, has provided us with the atomic coordinates of the pigments and some details about their interactions with neighboring aminoacid residues. This essential step has given a large impetus both to experimentalists and to theoreticians who are now attempting to relate the X-ray structural model to the optical properties of the reaction center and ultimately to its primary biological function.

Download or read book Light induced Conformational Changes in the Photosynthetic Reaction Center from Rhodobacter Sphaeroides written by Sasmit S. Deshmukh and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The photosynthetic reaction center (RC) from purple photosynthetic bacteria is a membrane-bound protein-pigment complex that serves as an excellent model for studying biological energy conversion. This energy conversion takes place by electron transfer reactions, which occur within the protein and are often coupled to conformational changes. In order to study these conformational changes, recovery of the oxidized bacteriochlorophyll dimer, from the RC of the purple photosynthetic bacterium Rhodobacter sphaeroides, to its original state was measured by light-minus-dark optical difference spectroscopy. Laser flash excitation generated an electron transfer that takes place across the membrane; creating the primary charge-separated state with a lifetime of 100 ms. Prolonged illumination induced subsequent conformational rearrangements in the RC protein complex which result in lifetimes of the same charge-separated state that are significantly different from that measured after flash excitation. The structural details of the conformational rearrangements on the molecular level will be discussed. The conformational changes were sensitive to duration and wavelength of illumination, pH, temperature, hydrophobic environment (liposome or detergent), head-group charge of the detergent, and presence of a bound metal ion. By systematically varying these parameters, we were able to extend the lifetime of the charge-separated state up to 21 mins. Based on these results, our goal is to utilize the bacterial RC protein complex as a biocapacitor, since the positive and negative charges are separated by a hydrophobic core of the protein with a low dielectric constant. This biocapacitor can be discharged rapidly by inducing pH jump.

Download or read book Photosynthesis written by G. Garab and published by Springer Science & Business Media. This book was released on 1998-12-15 with total page 884 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photosynthesis is a process on which virtually all life on Earth depends. To answer the basic questions at all levels of complexity, from molecules to ecosystems, and to establish correlations and interactions between these levels, photosynthesis research - perhaps more than any other discipline in biology - requires a multidisciplinary approach. Congresses probably provide the only forums where progress throughout the whole field can be overviewed. The Congress proceedings give faithful pictures of recent advances in photosynthesis research and outline trends and perspectives in all areas, ranging from molecular events to aspects of photosynthesis on the global scale. The Proceedings Book, a set of 4 (or 5) volumes, is traditionally highly recognized and intensely quoted in the literature, and is found on the shelves of most senior scientists in the field and in all major libraries.
